To investigate the safety of laparoscopic techniques for right colon cancer surgery and to explore the clinical outcomes by using different approaches.

A retrospective analysis was performed in 145 patients who underwent radical resection of right colon cancer from May 2012 to May 2017. According to the surgical approach, patients were divided into routine approach group (n=47, intermediate approach), into lateral approach group (n=53, lateral approach) and open surgery group (n=45). The data were analyzed by using SPSS20.0 software. Measurement data such as perioperative relevant indicators and immune function indicators were expressed as (±s) and were examined by independent F test. The incidence of complications were examined by chi square test. A P value of <0.05 was considered as statistically significant.

The amount of bleeding, the number of lymph nodes, and the time of exhaustion in the lateral approach group were significantly better than those in the open group and the routine approach group respectively(P<0.05). Hospitalization time, analgesia time and the total incidence of complications in the lateral approach group were significantly better than those of the open group respectively (P<0.05), however there was no significant difference between routine approach group (P>0.05). In terms of operation time, the open surgery group was significantly lower than the other two groups (P<0.05). After treatment, the immune indexes such as CD4, CD8, CD4/CD8 of the three groups were significantly improved (P<0.05). The indexes of patients in the lateral approach group were significantly better than the other two groups (P<0.05).

The clinical effect of lateral approach in laparoscopic radical resection of right colon cancer is remarkable, which could reduce complications and improve immune function. It is safe and reliable and worthy of further promotion and application.
